Modifying DataBound Hyperlinks Text

Modifying a GridView's Databound Hyperlink text since I couldn't do this easily in the ItemTemplate, I moved the Replace function to the DataBound of the GridView:

    protected void GridViewStocksInLists_DataBound(object sender, EventArgs e)
    {
        int rowId;
        string imgUrl;
        string navUrl;
        for (rowId=0; rowId<GridViewStocksInLists.Rows.Count;rowId++) {
            imgUrl = string.Empty;
            navUrl = string.Empty;
            imgUrl = ((HyperLink)GridViewStocksInLists.Rows[rowId].FindControl("hlChart")).ImageUrl.Replace('$', '^');
            ((HyperLink)GridViewStocksInLists.Rows[rowId].FindControl("hlChart")).ImageUrl = imgUrl;
            navUrl = ((HyperLink)GridViewStocksInLists.Rows[rowId].FindControl("hlChart")).NavigateUrl.Replace('$', '^');
            ((HyperLink)GridViewStocksInLists.Rows[rowId].FindControl("hlChart")).NavigateUrl = navUrl;
        }
    }

This replaced $ with ^ in my HyperLink.

Here is the GridView that contains the HyperLink:

<asp:GridView ID="GridViewStocksInLists" runat="server" DataSourceID="SqlDataSourceGetStocksInList">
                    <RowStyle CssClass="tableAnalysisRow" />
                    <HeaderStyle CssClass="tableAnalysisHeader" />
                    <AlternatingRowStyle CssClass="tableAnalysisAlternatingRow" />
                    <Columns>                  
                        <asp:TemplateField HeaderText="Chart">
                            <ItemTemplate>
                                <asp:HyperLink ID="hlChart" runat="server"
                                ImageUrl='<%# Eval("Symbol", "http://chart.finance.yahoo.com/c/0b/d/{0}").ToLower() %>'
                                NavigateUrl='<%# Eval("Symbol", "http://finance.yahoo.com/q/bc?s={0}&t=1y").ToLower() %>' >
                                </asp:HyperLink>
                            </ItemTemplate>
                        </asp:TemplateField>
                    </Columns>
                </asp:GridView>
